winedump

[Eric Pouech <eric.pouech@wanadoo.fr>]

this patch slightly changes the winedump command line parsing
it used to only accept command line of the form:
winedump <cmd> <file or arg> <options for cmd>

it now allows form like:
winedump <cmd> <options for cmd> <file or arg>
which is more natural, and allows for running winedump from
find | xargs -n 1 winedump ....

A+
